Coastal railway line, Israel


The Coastal railway line is a mainline railway in Israel, which begins just south of the Lebanon-Israel border on the Mediterranean coast, near the town of Nahariya in Northern Israel and stretches almost the entire Mediterranean coast of the country, to just north of the border with the Gaza Strip in the south.

History

The northern part of the coastal line from Acre to Remez Junction was built by the British during the 1920s and operated by Palestine Railways. In 1941–42 engineers of the South African Army and New Zealand Army extended the line north to Beirut and Tripoli, Lebanon through railway tunnels at Rosh HaNikra grottoes. Following the 1948 Arab–Israeli War the tunnel linking the line to Lebanon was blocked.
The section south from Remez junction including its then-terminus, the Tel Aviv Central Railway Station, were built by Israel Railways in the beginning of the 1950s and the new line opened in May 1953 with Tel Aviv Central opening in November 1954. This new railroad then became the main north-south rail link between northern and central Israel, supplementing the older, more easterly/inland section which connected Remez junction and the nearby Hadera East Railway Station to the Lod Railway Station in central Israel that was constructed during the Ottoman period. This new section of coastal railway from Remez junction linked the Tel Aviv Central Station and Haifa Central Railway Station and significantly shortened the travel time between the two cities as well as providing rail service to the cities of Herzliya and Netanya.
Little development of the line followed for the next forty years until 1988 when works started on extending the railway southwards from Tel Aviv Central along the Ayalon Highway. The new railway section, about 5 km in length, was opened in 1993 as the Ayalon Railway; passing through the heart of Tel Aviv, it quickly became the busiest railway line in Israel. It was the first railway line in Israel to be double-tracked from the outset, allowing up to 8 trains per hour in each direction; but even that proved insufficient, and by 2 November 2006, the entire section had been widened to triple-track, increasing the capacity to 14 trains per hour in each direction. A project has been approved to add a fourth track to the line, narrowing the conduit of Ayalon River to make room for the new track, and diverting the excess rainwater into specially-constructed reservoirs.
The opening of the Ayalon Railway, extending the Coastal Railway to connect with the Jaffa–Jerusalem railway, heralded a new era of railway development in the country as it allowed trains from the north to reach the south of the country through, rather than around, the nation's largest metropolis. Along this new railway section, two additional stations were built: Tel Aviv HaShalom opened in March 1996, and Tel Aviv HaHagana on 22 June 2002. During the construction of the Ayalon Highway, a provision was made for a third station between these two, at Yitzhak Sadeh bridge – although this station has yet to be built.
Over the years additional stations were built along the line, including Hadera West, Haifa Hof HaCarmel, Tel Aviv University, Caesarea-Pardes Hanna, Lev HaMifratz and Hutzot HaMifratz.
A new section that includes six new stations along the South Ayalon Highway and Highway 4 was constructed in the early 2000s and connected the Coastal Railway with Ashdod Ad Halom railway station of the Lod–Ashkelon railway. The first phase of this work involved extending the coastal railway from the Tel Aviv HaHagana railway station to the new Rishon LeZion Moshe Dayan railway station, serving the southern Tel Aviv area suburbs and opening for service in September 2011. The remainder of the route to Ashdod opened in 2013, with the intermediate Yavne West railway station having opened in early 2012. This last section features a long cut-and-cover tunnel south of Yavne and a large flying junction at the intersection of the new coastal railway with the Lod–Ashkelon railway and the railway branch to the Port of Ashdod. From Ashdod, the existing railway from Lod extends south along the coast to near Yad Mordechai through Ashkelon. From Yad Mordechai the new Ashkelon–Beersheba railway, completed in 2015, branches inland southeastwards through the northern Negev.
Beginning in the late 1980s, works started to double track the line in stages. These were finished in 2013 when double tracking works on the railway section between Akko and Nahariya were completed. Nowadays the line consists of at least double track throughout its entire length.

Services

Both intercity and suburban services operate on the line. The intercity service from Nahariya and Haifa to Tel Aviv and suburban services in both the Tel Aviv metropolitan area and the Haifa metropolitan area. Freight trains operate on the line as well.
The line is the busiest on the Israel Railways network, with the section along the Ayalon Highway the busiest on the line.

Plans

Electrification

Plans exist to electrify the line, though the Haifa municipality continues to oppose them due to aesthetic and public access reasons since the railway lies so close to the coastline within its borders. Work on the Ayalon section between HaHagana and Herzliya, the busiest railway section in Israel and the first part of the Coastal Railway to be electrified started in HaHagana station in the fall of 2019 and reached Tel Aviv Central in Spring 2020.

Widening

Because the line is Israel's most congested, there are long-term plans to widen it to four tracks in stages between Tel Aviv HaHagana and Haifa. The section between Tel Aviv Central and Tel Aviv University stations already consists of four tracks, while works to extend the four track section from University to Herzliya were completed in 2020.

Ayalon bottleneck

The section between Tel Aviv HaHagana and Tel Aviv Central currently consists of three tracks. Many rail lines in Israel use this section which is operating at full capacity. This severely restricts the ability of Israel Railways to expand service to different parts of the country and constitutes a critical bottleneck in the entire national rail network. Given that this section is located in a dense urban environment and with the railway being bound by the Ayalon River and the Ayalon Highway on either side makes the addition of a fourth track an extremely complex engineering challenge.
After many years of deliberations on the matter, an NIS 5.5 billion project was approved in 2018 to add the fourth track to the Ayalon section by constructing an elevated platform over the channel of the Ayalon River to carry the new track. Since the platform will reduce the capacity of the channel to carry water, the project also includes large-scale drainage works to divert excess rainwater into specially-constructed reservoirs, including one on the grounds of Ariel Sharon Park, and a temporary reservoir on the grounds of the Mikveh Israel agricultural school southeast of Tel Aviv to be used until an underground pipeline can be constructed to divert the outlet of the Ayalon River from northern to southern Tel Aviv. The overall project also includes adding two additional tracks within a widened Highway 1 median extending from HaHagana to the Ganot/Shapirim interchanges.
Despite the urgency in adding the fourth track, due to additional necessary permits and approvals, the detailed design of the project, and extensive preparatory drainage works, construction is not expected to begin until the early-to-mid 2020s, with works expected to take place through at least 2026. The State Comptroller of Israel has harshly criticized the governmental planning authorities for the repeated delays associated with the construction of the fourth track, which is a critical missing element in Israel's public transportation infrastructure.

Other plans

A plan exists to rebuild the old Eastern line to act as a backup railroad to the coastal line south of Remez junction, while at other times to serve mainly freight trains with some limited passenger service.
